AUTOMATIC RAILWAY-SWITCH.

Specification of Letters Patent. Patented Aug. 21, 1917.

Application filed January 30, 1917. Serial No. 145,511.

To all who m it mag concern.

lie it known. that I, LOUIS EIsnNBnRc, a citizen of the United States, residingat San i-intonio, in the county of Bexar, State of Texas, have invented certain new and useful improvements in Automatic Railway- Switches; and I do hereby declare the following to be a full, clear, and exact description of th eii'ivention, such as will enable others skilled in the art to which it appertai'ns to make and use the same.

This invention relates to improvements in railway switches, and particularly to automatic railway switches for use in street railways or steam railways.

One object of the present invention is to provide a novel and simple device of this character and which is an improvement on the Patent 942,033, issued Nov. 30, 1909, to Jose Ma Godoy.

The particular improvement resides in the peculiar construction of the gear segments which actuate the transverse sliding bar, whereby there will be a larger and stronger surface to be acted upon by the car ca rried means.

Another object is to provide novel and efficient means for supporting the transverse bar whereby said bar will more quickly and properly respond to the impulse imparted to it by the gear segments.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

In the drawings:

Figure 1 is a planview of a portion of a railway with a switch, showing the application of my operating mechanism.

F i g. 2 is a transverse sectional view taken on the line 2-2 of Fig. 1.

Fig. 3 is a top plan view similar to Fig. 1. with the cover parts broken away.

Fig. 4 is a longitudinal sectional view taken on the line 4 -4 of Fig. 3.

Fig. 5 is a transverse sectional view taken on the line 55 of Fig. 3.

i Fig. 6 is a perspective view of one of the gear segments. f

Referring particularly to the accompanying drawings, 10 represents the rails of the main line, 11 the rails of the curve, and 12 the pivoted switch point. Disposed transversely under. the: main rails, at a suitable distance fromthe curve, is an elongated box 13, and extending between the rails, and

running in parallel relation thereto, is a boX '14, the same communicating with the first box, at a. point intermediately on. one side. In the bottom of each end of the first box 13 there is mounted a transverse roller 15, and supportedon these rollers is a transverse sliding rod 16, the upper portion of each end of which is formed with teeth 17. Pivotally mounted above eachtoothed portion of the rod 16 is a segmental gear 18 which meshes with said toothed portion. The upper end of each of the segmental gears is disposed immediately outward of the main rails 10 in position to be engaged by a wheel 19 carried by the car 20, and ar ranged to be lowered by the operator of the car. This upper end of the segmental gear is formed with a transverse head 21 which extends longitudinally of the rail, and has its upper face inclined downwardly longitudinally of the rail and away from the switch point, and also in a direction away from the rail.

One of these segments is arranged to be engaged by one of the wheels 19 to move the switch point in one direction, while the other wheel 19 is arranged to engage the other segment to move the switch point in the other direction.

The intermediate portion of the transverse rod 16 is elevated, as shown at 22, and formed with an opening 23 which receives the pin or lug 24 carried by the lever 25 which is centrally pivoted 1n the box 1 1. The other end of this lever is pivotally connected to the switch point by means of a link 26. Thus when one of the segments is rocked on its pivot the teeth thereof will, by their engagement with the teeth of the adjacent end of the sliding rod, move said rod and cause the shifting of the switch point through the lever 25 and link 26. The movement of the other segment returns the switch point to the position from which it was first moved. The segments are so arranged with respect to the toothed endsof the transverse bar or rod that when one of said segments is up in position to be engaged by the wheel 19 of the car, the other one is down, and that when the raised one is depressed the other one will be lifted. Thus one is always in elevated position.

The boxes are each provided with a suit able cover plate 27 and in each plate there are formed openings through which oil may be applied to the working parts of the the openings Which can be quickly andv easily removed when desired.

WVhat is claimed is: An automatic switch including a switch point movably mounted, a transverse sliding rod connected With the point and provided with toothed portions, gear segments movably mounted adjacent the toothed por- 10 tions and meshing therewith, said segments having transverse head portions the upper faces of Which incline longitudinally and laterally.

r In testimony whereof I affix my signature, in the presence of two Witnesses.
